Similar to storing documents and photos on Google Drive or Dropbox, iCloud is a “cloud” for document storage, where iPhone, iPad and Mac product users can store photos, documents, contacts and more, and synchronize the content between devices.

What makes iCloud different than other services is the automatic backup that happens when a user’s device is connected.

So even though a compromising photo may be deleted from an iPhone’s camera roll, it can still show up in the “My Photo Stream” section, and be automatically uploaded to the mobile phone user’s linked iCloud account when plugged into a computer or when plugged in and connected to WiFi, depending on the user’s settings.
